Tag View is fine, maybe that means kioslave is fine too.

I discarded all changes, and it still doesn't work...
I tried enabling and disabling icon view filters, and still no change...
I tried to turn on kdebugdialog, it gives:

digikam(27252)/digikam (core) Digikam::SearchTabHeader::keywordChanged:
same keywords as before, ignoring...
digikam(27252)/digikam (core) Digikam::SearchTabHeader::keywordChanged:
keywords changed to ' "2012" '
digikam(27252)/KGEOMAP KGeoMap::ItemMarkerTiler::slotSourceModelReset: ----
digikam(27252)/digikam (core) Digikam::SearchTabHeader::keywordChanged:
keywords changed to ' "2012" '
digikam(27252)/digikam (core) Digikam::SearchTabHeader::keywordChanged:
same keywords as before, ignoring...

seems fine...

And please tell me what SearView is, because I haven't found that...
But I tried debugging in QtCreator, the query is:
<?xml version="1.0"?><search><group><field name="keyword"
relation="like">2012</field></group></search>\n
